SPINNING BALANCED LOADS
Your centrifuge must contain a balanced load in order to work properly.
Use the following rules when loading the rotor.
Spinning balanced loads will extend the life of the machine and produce
better results.
1. Opposing tube holders must be identical and must contain the
same cushion, or none at all.
2. Opposing tube holders must be empty or loaded with equally
weighted samples.
3. If an odd number of samples is to be spun, fill a tube with water
to match the weight of the unpaired sample and place it across
from this sample.
ROTOR REMOVAL AND INSTALLATION
TO REMOVE THE ROTOR:
1. Unlock the centrifuge by pushing the ‘OPEN / STOP’ button and
unlatch and open the lid.
CAUTION: Unplug the centrifuge from the electrical outlet to
eliminate the possibility of electrical shock or other injury.
2. Remove the test tube holders.
3. Remove the nut in the center of the rotor by turning it
counterclockwise (a tool may be required).
4. The rotor is sitting on a cone-shaped adapter. Pull the rotor up
and off of this adapter.
TO INSTALL THE ROTOR:
1. Place the rotor back onto the cone-shaped adapter. You may
need to turn the rotor slightly to line it up properly.
2. The rotor should slide onto the rotor cone freely.
3. Once a proper fit has been achieved, replace the nut and turn it
until it is hand-tight, (a tool may be required).
4. Replace the tube holders and verify that they are seated
properly.
5. It is recommended that the initial setup procedures be
performed to ensure that the rotor has been installed correctly
and that no damage has been done to the centrifuge during
either the rotor installation or possible rotor chamber cleaning.
See page 6 for this procedure.

CARE AND PREVENTATIVE MAINTENANCE
With proper care and maintenance your centrifuge will provide years of
laboratory service. For proper care, the following steps should be taken:
1. Provide Adequate Ventilation: For cooling purposes, the Model
614VET draws in ambient air through the air intake cover on the
top of the lid and exhausts this air in the rear of the base. The
centrifuge should be placed on a hard smooth surface for good
air circulation.
2. Always Spin Balanced Loads: Make certain that you are always
spinning a balanced load. The Model 614VET has a unique
counter balanced motor mounting design which, along with its
rubber suction feet, produces excellent vibration dampening.
However, out–of–balance loads may break glass test tubes and
may produce unsatisfactory separation results. Proper load
balancing will improve sample separation and extend the life of
the centrifuge. Refer to page 10 on balanced loads for additional
information on balancing the load.
3. Keep the Tube Holders Clean: NOTE: Always follow the safety
guidelines of your laboratory to properly clean up and/or dispose
of materials in the event that a substance known to be
potentially toxic, radioactive or contaminated with a pathogenic
microorganism is spilt in or on the centrifuge. Small glass
fragments left in the tube holder after a tube breakage may
adhere to the next test tube inserted in that holder. When this
tube is handled, these fragments may puncture protective gloves
and lacerate the operator’s fingers or hand. Remaining fragments
may provide stress points on subsequent tubes and result in
additional breakage. If a tube breakage occurs, carefully remove
the tube holder. Properly dispose of the sample and tube
fragments and thoroughly clean both the inside and outside of
the tube holder. Insert a new tube cushion (if necessary) and
replace the tube holder in the rotor.
4. Motor and Electrical Maintenance: The Model 614VET uses a
brushless permanent split capacitor AC motor. It should not need
routine servicing for the life of the centrifuge. The electrical
components are selected for high reliability and should not need
routine service.
5. Tube Holder Replacement: It is recommended that the tube
holders be replaced after 24 months of use. Inspect tube holders
regularly for cracks. If cracks are discovered, replace
immediately.

Drucker Diagnostics [phone] - [e-mail] Page | 12
6. Remove Accessories Before Moving: All tube holders, samples,
and caps must be removed from the rotor chamber before
transporting or storing the centrifuge to prevent damage and
injury.
CLEANING AND DISINFECTION
To prolong the life of the centrifuge cleaning and disinfection is
recommended every six months, or whenever there is a spillage or tube
breakage. Contaminants must be removed immediately, or corrosion and
premature degradation of components can occur.
1. Unplug the centrifuge before cleaning.
2. Apply cleaning solutions with a towel or cloth. Do not submerge
the centrifuge in water or other cleaning solutions as this will
cause damage and void the warranty.
3. ONLY isopropyl alcohol, soap and water, or a 10% (5500 PPM)
bleach solution should be used for cleaning and disinfection of
the centrifuge and accessories.
4. All surfaces must be dried immediately after cleaning and
disinfecting.
5. TBQ Germicidal products shall not be used, as they will cause
damage to the centrifuge and void the warranty.
6. The use of fully/partially halogenated hydrocarbons, ketones,
esters, ethers, benzyls, ethyl benzenes, and all other chemicals
not prescribed by the manufacturer shall not be used as they
may cause damage to the rotor chamber, rotor, tube holders,
accessories and centrifuge exterior and void the warranty.
7. It may be necessary to remove the rotor and clean the rotor
chamber. Follow the instructions on page 10 to remove and
reinstall the rotor.

Drucker Diagnostics [phone] - [e-mail] Page | 14
The machine does not unlock
after a run has completed.
The lid should remain locked until
the rotor has nearly come to a
complete stop and then unlock
for 60 seconds. If additional
unlock time is needed, press the
’OPEN/STOP’ button with
the machine plugged in and the
rotor stopped. If the lid remains
locked after this and will not
unlock, the electronics may have
been damaged. Contact Drucker
Diagnostics for assistance. To
access the rotor chamber, follow
the procedure on page 14,
“Emergency Rotor Chamber
Entry”.
The run time is not set to the
desired length.
Check the run preset by following
the instructions on page 8. If the
preset is not the desired length,
follow the procedure on the same
page to change the run preset
time.
EMERGENCY ROTOR CHAMBER ENTRY
In the event of power failure, it may be impossible to unlock the lid by
conventional means. In this case, entry into the rotor chamber may be
made by removing the latch label and using a
pen to manually disengage the locking
mechanism (see photo). Pull the mechanism
towards the control panel and then unlatch
and open the lid. If the unit is damaged,
contact your authorized dealer or Drucker

SAFETY
The Model 614VET complies with US, Canadian, and European Safety standards.
Lid Safety Switch: The Model 614VET lid is secured to the top of the
cabinet by a latching knob and pawl system. When the knob is rotated
clockwise, the pawl grips the underside of the cabinet opening and
prevents the lid from opening. A mechanical stop positions the pawl and
prevents it from rotating completely. When rotated to the stop position,
the pawl makes contact with a micro–switch mounted underneath the
cabinet top. The lid safety switch prevents the centrifuge from operating
while the lid is open. An indicator light on the front of the machine will
light up when the lid has been latched properly.
Lid Safety Interlock System: In addition to the Lid Safety Switch, the
Model 614VET has a true “0 RPM” lid locking system. The lid safety
locking system keeps the lid locked at all times, (even during power
failure), and requires that the rotor be at rest in order to unlock the lid.
The centrifuge will not allow entry into the rotor chamber unless the
centrifuge has power and the rotor is stopped. To open the lid, make sure
that the centrifuge is plugged in and, with the rotor stopped, press the
‘OPEN/STOP’ button.
Note: After the centrifuge has started spinning, it may be possible
to rotate the lid knob enough to cause the pawl to lose contact
with the lid safety switch. If this happens, the centrifuge motor
may lose power, but the lid will still remain locked. If the knob is
accidentally moved and this situation should occur, rotate the
knob fully clockwise to its stop position and the centrifuge will
resume operation.
Circuit Breaker: The Model 614VET is protected with a 5 Amp circuit
breaker located at the rear of the machine mounted to the base. Any
electrical short circuit will cause the breaker to cut power to the machine.
